ROSACEA. 439 



are found in the barks of several Rosacecs, hence used either in medi- 

 cine or for tanning or dyeing. The Bird Cherry' {Yr.,Putiet, Merisier 

 a grappes), a tree spontaneous in Europe, has a strong-smelling bark 

 of bitter astringent taste, which has been proposed as a succeda- 

 neum to quinine in the treatment of intermittent fevers. The bark- 

 of the Virgina Cherry^ is supposed to be endowed with the same 

 properties. They are met with in P. Capolina* a Mexican species, 

 pointed out as a good substitute for quinine. Marf/yricarpm 

 setosus^ from Chili and Peru, is also an astringent plant, for 

 in its native country it is used against piles. The Chrysohalaneai 

 share these properties, so widely diffused in the whole order 

 Rosacea. Chrysohalcmus Icaco^ is valued for its root, bark, and 

 leaves, which are considered in Brazil and the neighbouring countries 

 as efficacious in the treatment of diarrhceaic and leucorrhoeaic affec- 

 tions, and certain other forms of flux. 



It is for the same reason that several Rosacea serve for pre- 

 paring hides and dyeing black. The Brazilians obtain this colour 

 by treating the fruits of Licania glabra and heteromorpha with fer- 

 ruginous earths. The mesocarp of Chrijsohalanus and that of 

 Couepia clirysocalyx also serve to make a deep black, with which the 

 Indians cover the vases they make from Calabashes and Gourds." 

 In our country a yellow or black dye is obtained from the bark 

 of several Pyrea, especially of the genus Cratcegiis ; so with the 

 genus Pliotiiiid in India. We must also cite as tinctorial species 

 more or less frequently used, the Crab-apple {Pyriis acerba DC), 

 and the White Beam {P. Aria Cii.) ; the Roses when covered with
